Figure 1. All the figures show trajectories of z_jfor K = 5.

(a) and (c) are in the complex plane with the abscissa and ordinate meaning the real and imaginary part, where p = 0.4 in (a), p = 0.9 in (c). (b) and (d) are time history with the same p as (a) and (c), where A represent active elements, I represent inactive elements, all represent both active and inactive elements.
